[sdiy] Dual power supply solution? - Kits vs 2600

[tomg]

Actually a VRef in a VCO4 would screw it up for use at different supply
voltages. Reset is at 1/2 the supply. This changes with the supply voltage
if you use a opamp divider. A VRef wouldn't allow for that unless you
wanted to trim for each oscillator. The vco3 has no dependant tri output
so it wouldn't matter.  I blanket statements that this or that is absolutly
better
is a looser. It some cases it may be true but not always.
